A piston pump for dispensing fluid from a reservoir, an improved vacuum relief arrangement in which a passageway for flow of air from the atmosphere into the reservoir is provided at least in part through a piston-forming element of the piston pump.

An apparatus for transferring a beverage from a sealed container into a storage vessel includes a needle for insertion through a stopper of the sealed container having a conduit for the flow of beverage through the needle and a pressurisation mechanism configured to pressurise the sealed container to displace the beverage through the needle and into the receiving vessel in use. The apparatus is configured so that, when the needle is inserted into the sealed container and connected to the storage vessel, the sealed container, needle and storage vessel form a closed system, allowing the beverage to be transferred from the sealed container into the storage vessel without air outside of the closed system mixing with the beverage.

In one implementation, a fluid injection system for wellhead sites includes a pump, a pump manifold, and a flexible hose coupled between the pump and the pump manifold. The flexible hose includes a first end coupled to the pump and a second end coupled to the pump manifold. The first end of the flexible hose includes a first end fitting coupled to the pump, and the first end fitting is oriented at an angle relative to a horizontal plane. The second end of the flexible hose includes a second end fitting coupled to the pump manifold, and the second end fitting is oriented vertically and perpendicularly to the horizontal plane.

Device and method for filling pressurized gas tanks, particularly vehicle pressurized hydrogen tanks, the device comprising a liquefied gas source, a transfer circuit comprising two parallel transfer lines each having an upstream end linked to the liquefied gas source, at least two separate downstream ends intended to be each removably connected to a tank to be filled, each of the two transfer lines comprising: a pump, a vaporizer for evaporating the pumped fluid, a branch for bypassing the vaporizer and a distribution valve(s) set configured to control the flow of fluid pumped and distributed between the vaporizer and the branch line, the device further comprising a storage buffer(s), which storage buffer(s) is(are) connected in parallel to each of the two transfer lines via a set of valves.

A fluid transfer device is implemented which has an inlet for receiving a fluid from a subject container or reservoir and an easily controllable outlet to direct the received fluid to a desired location, such as a target container or reservoir. The inlet and outlet may both include conical spouts to which various sized hoses can removably attach to enable directional and maneuverable control for a user. The fluid transfer device includes a base which rests on a surface and provides support for the components above it, including a handle and an operational arm that handles the fluid transfer operations. The fluid transfer device is configured with versatility for adaptability to multiple use cases. For example, the fluid transfer device has a height-adjustable handle to accommodate differently sized containers, a hinged operational arm, and a horizontally-adjustable container rest.
